Further rigorous security checks have been implemented ahead of the tournament's March 12 start, including an audit earlier this week, ticking off what sort of police force numbers are being provided as well as the level of resources dedicated to protecting players in each of the 12 host cities.
Certainly the IPL's vast salaries now have the whiff of danger money about them, thanks to threats from organisations such as the Al Qaeda-allied 313 Brigade and Shiv Sena. This is also the first IPL to be played since the Mumbai terror attacks of November 2008.
New Zealand Cricket Players Association boss Heath Mills says efforts have been reinforced on the ground to get the right methods in place to deliver the security management plan.
"If this momentum for action continues over the next week leading into the event, you would think it would be at the security level you'd expect. The feedback we've given to the players in the last three days or so is that things seem to be improving."
"It's frustrating that it's happened so late," says Mills.
"Usually we have a process in place with New Zealand Cricket to manage the security situation on tours six months out. We conduct on the ground checks with independent security experts. One advantage of India, though, is that things can be done quickly when need be."
Ultimately Shane Bond, Brendon McCullum, Jacob Oram, Ross Taylor and Daniel Vettori now need to make the decision themselves.
Normally, ahead of an overseas tour, NZC would make the overall decision but on this occasion the players are independent contractors.
"Given the work over the last couple of weeks they'll be a lot more comfortable," says Mills. "But I couldn't say whether they will go or not. That's their decision. We just provide them with information."
While four of the New Zealand players will get an initial opportunity to watch from a distance, Bond will be the first to decide whether to head up following the conclusion of the Chappell-Hadlee one-dayers next Saturday.
IPL chairman Lalit Modi would not comment on the current security arrangement, referring the issue instead to his vice-chairman and former secretary of the Indian Cricket Board, Niranjan Shah.
"We are concerned, but I think there will be no problem with foolproof security," Shah says.
